The TDK B25620B0557K881 is a high-power MKP DC film capacitor designed for demanding power electronic applications such as inverters, motor drives, and DC-link circuits. It features a dry-type, non-PCB polyurethane resin filling and a robust aluminum case with an M12 mounting stud. This capacitor offers high current handling, low ESR, and a long service life expectancy of 100,000 hours at +75°C.

Key Features

  • High Power Density: Compact design with high capacitance and voltage ratings.
  • Low Loss: Very low dielectric dissipation factor (tan δ) of 2 x 10-4.
  • High Ripple Current: Capable of handling high RMS and peak currents.
  • Robust Construction: Aluminum case with M12 stud for secure mounting, suitable for high-vibration environments.
  • Long Service Life: 100,000 hours at +75°C hotspot temperature and rated voltage.
  • Wide Temperature Range: Operational from -55°C to +85°C.
  • Safety Compliant: Certified to UL 810 5th Edition (File E183224).
